4.3.1 BAU Meter Wiring Diagrams

Transcription

1 4.3.1 BAU The following provide details of the wiring of metering on New Connections for new customer installations, and Additions / Alterations to existing customer installations undertaken as Business as Usual (BAU) activities, and to comply with the CitiPower and Powercor Tariff rules. New Connection customers typically receive a single element, single meter for connection to a General Power and Light Time of Use Network Tariff, such as C13R in CitiPower or P13R in Powercor, or a Flat Rate Network Tariff, such as C1R in CitiPower or D1 in Powercor. Those single phase New Connection customers installing an approved off-peak storage electric hot water service can chose to connect via use of a single phase single element meter on a Time of Use Network Tariff or access a Dedicated Circuit Controlled Load Tariff arrangement through via use of a single phase two element meter and relevant Network Tariffs such as C1RCDS in CitiPower or D1DD1 in Powercor. Note: Customers undertaking a meter exchange as part of an Additions / Alterations retain all existing tariffs and dedicated circuit load control arrangements. Load Switching - Single Phase New Connections & Additions / Alterations. Single phase New Connection customers, and existing customers undertaking an addition/alteration but remaining as single phase installations will be provided with a switching service for eligible single phase off-peak hot water units up to 30A, inclusive of boost tails (if permitted by the Retailer). For those Single phase New Connection customers with an approved off-peak storage hot-water unit and requesting access to a Flexi tariff such as C13R in CitiPower or P13R in Powercor will be connected via a single phase single element meter, with the HWS connected to the meter s contactor (inclusive of boost tails if permitted by the retailer), and the hot-water unit will continue to be switched and charged at the off-peak rates each night between 11pm and 7am, any re-heat consumption will be charged at the prevailing Time of Use rates. All consumption will be recorded on the E1 data stream and display register #3. - Page 1 of 14

2 For those Single phase New Connection customers with an approved off-peak Electric Hot Water service and requesting access to a Dedicated Circuit Controlled Load Tariff arrangement, will be undertaken via a single phase two element Meter, with the HWS connected to the meter s contactor (inclusive of boost tails if permitted by the retailer), with the HWS consumption charged at the Dedicated Circuit Network Tariff off-peak rate, including any HWS top element re-heat. GP&L consumption will be recorded on the E1 data stream and display register #3, while HWS consumption will be recorded on the E2 data stream and display register #7. Load Switching - Multi Phase New Connections & Additions / Alterations. Multiphase New Connection customers, and existing customers undertaking an addition/alteration resulting in multiphase phase installations will be provided with a 2A switching service for single or multiphase loads controlled by a customer owned contactor. Customers will need to provide a 2A circuit breaker and their own load control contactor within the customer s own switchboard in accordance with Figure 1. Loads controlled by the 2A Switching Service will continue to be switched and charged at the off-peak rates each night between 11pm and 7am, any boost consumption will be charged at the prevailing Time of Use rates. All consumption will be recorded on the E1 data stream and display register #3 of the Meter. Multiphase meters are only available in a single element form, and consequently New Connection customers cannot access a Dedicated Circuit Load Control Tariff, and hence those sites using load control are recommended to apply for a ToU tariff such as Flexi tariff C13R in CitiPower or P13R in Powercor. - Page 2 of 14

3 Boost Button: All AMI meters with contactors have a boost button, and in all HWS applications cases, the customer can press the manual boost button on the meter, which will close the contactor for up to 6 hours (or until the HWS thermostat disconnects supply) however that consumption will be recorded on the E1 data stream and display register #3 of the Meter and on the prevailing rate of the General Power and Light Tariff. Approved Off-Peak Electric Storage Hot Water Services The dedicated circuit controlled load tariff and switching times are designed around the heating requirements of an 8 hour hot water storage unit, limited to a 30 amperes, resistive current rating and turned off and on in accordance with the applicable CitiPower and Powercor load control strategy. Smaller storage hot water services (i.e. less than 8 hour heating times) will switch-off via their thermostats (as will an electric boosted solar hot water service) and therefore, will operate satisfactorily on two element meters and tariffs. These controlled load tariffs are not suitable, nor available for use with heat pump technology hot water services, or slab heating / heat bank equipment requiring an afternoon boost. (Existing customers are able to retain their existing Slab/Heat bank arrangements) - Page 3 of 14

6 Bi-directional Metering for Embedded Generation All bi-directional metering in CitiPower / Powercor is provided as net metering, and connected on the General Power and Light supply, gross metering for embedded generation is not provided. Solar (VFIT) Metering, and Load Control The Victorian Feed in Tariff (VFIT) is available to new solar customers (and existing solar customers transferring from PFIT, TFIT or SFIT) and provides a feed in price from the Retailer in the order VFIT applications are permitted to remain on their existing Network consumption tariffs and to retain all existing load control arrangements via the metering. VFIT applications for existing customers will have their existing AMI metering reconfigured remotely for bi-directional metering. New solar customers with old analogue metering are required to have it replaced with a like for like bi-directional AMI metering installation to maintain access to existing tariffs and those existing load control arrangements. Requirement for Bi-Directional Metering: The requirements to upgrade the existing meter to a bi-directional meter arises from the National Electricity Rules, administered by the Australian Energy Market Commission (AEMC), an independent authority of the Federal Government and under the guidance of the Council of Australian Governments (COAG). NER Chapter 7 clause Metering installation components (a) A metering installation, unless it is classified as an unmetered connection point in accordance with schedule 7.2, must: (7) be capable of separately recording energy data for energy flows in each direction where bi-directional active energy flows occur or could occur; Note This clause is classified as a civil penalty provision under the National Electricity (South Australia) Regulations. (See clause 6(1) and Schedule 1 of the National Electricity (South Australia) Regulations.) - Page 6 of 14
